Biography
Omar Mateen was born in Port St. Lucie, Florida, United States to Sunni Muslim immigrants from Afghanistan. Mateen was inspired by Islamism, and he pledged allegiance to the Islamic State terrorist group; Mateen formulated a well-planned attack on the "Pulse Orlando" gay club in Orlando, Florida. At 2:00 AM on 12 June 2016, he began a mass shooting at the nightclub against the crowds of gay clubbers; this incident coincidentally occurred the day after Youtube singer and The Voice contestant Christina Grimmie was murdered in the same city. Mateen took hostages and claimed that he had explosive devices, holding back police and crisis negotiators sent to the club. The SWAT stormed the building and killed Mateen, who wounded one officer in the ensuing shootout; a controlled explosion occurred, and the hostages were freed. At least 20 people were killed in the shooting, while at least 42 were wounded; it was considered to be the worst terrorist attack on US soil since 9/11, surpassing the 14 casualties of the attacks in San Bernardino, California on 2 December 2015.
